Saab Key Programming

Saab cars manufactured since 1994 have an immobilizer feature that is based on codes for keys. A new transponder is required in order to enable the addition of an additional key, as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

The problem is that this could be very costly. It is recommended to always have a spare set of keys available.

Transponder key

The transponder keys are keys equipped with an electronic chip. It sends a signal to the car when it is placed in the ignition. The car then examines the signal to see if it matches that of the key. If the signals match then the car will be able to unlock and begin. This is a great method to guard your car against theft.

Transponder keys may be an extremely popular accessory for cars, but they are not as safe as traditional keys made of metal. While the metal parts of a traditional key could be cut and copied the transponder is protected by an electronic chip. The chip contains a unique code which is programmed into a car's computer order to identify it.

When a Saab key fob is used the car recognizes it and allows it to turn on. The car can only recognize the key fob when it has a chip that is unmodified and programmed to match. The car will not start if the key is not programmed to match.

It is vital to have a spare Saab key. This is particularly important especially if you reside in a rural area where there are many car thieves. The good news is that you can find a new key for your Saab without needing to visit a dealer and pay the expensive prices that they charge. In the majority of instances, you can get a new key created on-the-spot for less than half the cost you'd pay at dealerships.

Key for Wired


Saab cars usually come with two keys upon purchase. If you have only one, you need to purchase an additional key as fast as you can. This is because, if it's lost the car will require an entirely new CIM and the locking cylinders replaced. This could be expensive, especially if you are buying a second-hand car.

The next step is to connect the wires of the column and row to the microcontroller. This is the most laborious part of the project and will require a lot of soldering. It's not a common way to go about it, but you need to determine how to route and connect each column and row. For this keyboard, there are 5 rows and 17 columns. This means there will be 22 microcontroller wires and pins that you need to connect.

After the rows and column are soldered together after which it is time to connect the key switches. To do this you must place a diode on each pin on the key switch and solder it. This will protect the key switch pins from current and stop them from being shorted. A diode allows the current to flow in a single direction, and has a a black band visual indicator that shows the direction in which current will flow.

Sanabria says that a few of the tools available in auto parts stores, like the Autel MaxiIM IM608PRO or IM508 will assist shoppers or DIY customers to program replacement keys and restore data from the immobilizer. The tools connect to OBD ports and help the customer through each step, making the process easier than replacing the car's computer.

Jump-starting the battery

A majority of people keep an item in their trunk to jump start a car in an emergency, but it may not be a good idea for newer cars. These cars are equipped with a variety of computers and digital devices which communicate with each other. A surge in voltage when the battery is connected to another could cause damage to the components and render your car unable to drive.

Connect the cables to the vehicle operating. Allow it to run for two minutes. Attach the red clip on the positive terminal of the good battery. (It will say "POS" or "+".) Attach the other end to a clean unpainted metal surface under the hood of your disabled vehicle. The engine block is a good option. The black cable should not be connected to the negative terminal of the dead battery. saab key code www.g28carkeys.co.uk could create sparks, which could ignite gasoline in the engine compartment.

Once the cables are connected, you can begin the car and let it run for approximately five minutes. Then disconnect them in reverse. The battery in your Saab 9-3 will be recharged as you drive. It may take a while it to return to its original state. It is a good idea to invest in a spare key fob as soon as you can, since replacing the only working one requires the installation of a new computer module and special programming to convince it that the lost keys are not trying to steal the car.

Replacement Case

Saab owners often only have one car key, and if that is lost, they will be charged. The reason for this is that it's not cheap to replace a key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. In the event of theft, or any other disaster it is best to have an extra key. But don't buy a used key, even the case that it's "new." Keys that are claimed to be new from aftermarket sellers will not work and are likely to fail in the most critical moment.

Most locksmiths can't help you with a single working key, and the dealer will charge high prices to replace the computer in your car to create a replacement. We can reset and reprogram the EEEPROM of your computer to make it ready to accept a replacement key without the need to replace the entire system. This could save you a lot of money. It's also much less expensive than waiting until you lose your only key.
